Having an idea and building a solution is innovation, not entrepreneurship. "Entrepreneurs" are business people who take what someone else built and compete with other business people to sell it to the greatest market at the highest margins, then flog the business itself to some sucker just before it tanks. Someone who imagines and builds needs to be quite profound, whereas someone who takes and sells needs to be quite petty, so rarely do you find innovation and "entrepreneurship" in the same individual.
So I would say innovators are bad at finding their competition, which is the "entrepreneurs". Innovators often get a shock at how vicious "entrepreneurs" turn out to be when the product's almost ready. Even before there's a solution built, many "entrepreneurs" roam around looking for innovator victims who happily advertise what they're doing or even posting their software samples online. "Business is war" to the entrepreneur. Anyone in business who's building and trusting instead of stealing and fighting won't last long.
